4 Claims. l

My invention relates to air, gas, water, steam and oil pressure regulators, and has among its objects and advantages the provision of an improved vibration eliminator.

In the accompanying drawing:

Figure 1 is a vertical longitudinal sectional view of a conventional pressure regulator embodying my invention.

Figure 2 is a face view nator, and

Figure 3 is an edge View.

In the embodiment of the invention selected for illustration, Figure 1 illustrates a pressure regulator comprising a lower casing I and a dome I2 between which a diaphragm I4 is clamped, the casing IIJ and the dome I2 being xedly secured one to the other by bolts I6. The casing I0 includes a boss I8 internally threaded at 20 for connection with a fluid supply pipe, not shown; The casing also includes a wall 22 through which is threaded a valve orice 24. A valve 26 is seatingly related to the valve orice 24 and is connected with one end of a lever 28, this lever being pivotally supported at 30 in the casing I0.

The other end of the lever is pivotally connected at 34 with a lever plate 3B between which and a weight plate 38 is clamped the diaphragm I4, although the surrounding portion of the diaphragm is free to ileX in response to variable pressure conditions eiective thereon. A compression spring 40 has one end mounted on a post l2 located centrally of the weight plate 38, the other end of the spring having abutting engagement with a plug 44 threaded into a boss 48 on the dome I2. This plug may be adjusted to vary the tension of the spring 49. A cap 48 provides a closure for the boss.

A second boss 5U is provided on the dome I2 and is internally threaded at 52 for connection with an outlet conduit not shown. The incoming fluid enters the boss I8 and leaves through the boss 50, the flow of the fluid causing a pressure inside the casing I0 and the diaphragm I3 being responsive to such pressure, The construction so far described is old and well known in the art.

My invention comprises a vibration eliminator 54. While the vibration eliminator shown in the accompanying drawing comprises three equally spaced radial stems 5S, it may comprise any required number of stems, the number and relative spacing of the stems depending upon the action of the regulator. The stems 56 are attached to the post 42 and are arranged in a of the vibration elimplane paralleling the weight plate 38. To the outer ends of the stems 56 are pivotally connected eccentrics 58, all the eccentrics being of the same size, weight and shape. The eccentrics are arranged at right angles to their respective stems 56, and the pivotal connection between the eccentrics and the stems are located at the ends of the eccentrics.

Each eccentric includes a curvature 60 engaging the upper face of the weight plate 38, these curvatures beingl located intermediate the ends of the respective eccentrics, but remote from the free ends thereof, as shown in Figure 3, the opposite edges of the eccentrics are curved at 62 adjacent their free ends for engagement with theinner face of the dome I2.

My invention maintains practically a constant pressure at more than one point on the top of the regulator diaphragm since the spring 40 rests on the post 42. The curvatures 60 are spaced 120 degrees apart and apply adjustment spring tension at three equally spaced points circumferentially of the axis of the diaphragm, to maintain a stiiening force at these points between the flexible diaphragm and the rigid dome I2, thereby preventing vibration of the diaphragm and the regulating valve.

'Ihe invention operates as a stiffening device, to be inserted between the flexible diaphragm and the rigid body of a regulator, to eliminate the characteristic vibration of the flexible diaphragm and valve, thus eliminating the objectionable noise and the rapid wearing of the valve face.

Without further elaboration, the foregoing will so fully explain my invention, that others may, by applying current knowledge readily adapt the same for use under Various conditions of service.

I claim:

1. In a fluid pressure regulator, the combination of a housing having a iiuid inlet and a fluid outlet, a flow controlling valve, a pressure responsive diaphragm inside said housing operatively connected with said valve, a diaphragm vibration eliminator means yieldingly exerting pressure at a plurality of points on Said diaphragm, said diaphragm vibration eliminator means comprising a plurality of stems xedly connected to one another, eccentric members movably mounted on said stems, and resilient means interposed between said stems and the housing, said eccentric members having curved co-ntours respectively engaging the diaphragm and the housing.

2. In a iiuid pressure regulator, the combination of a housing having a iluid inlet and a fluid outlet, a ow controlling valve, a pressure responsive diaphragm inside said housing operatively connected with said valve, a Weight plate engaging one face of said diaphragm, a hub, stems attached to said hub, eccentric members rotatably mounted on said stems and respectively engaging said weight plate and said housing, and a tensioning spring interposed between said housing and said hub to yieldin'gly urge said eccentric members into said engagement with said weight plate.

3. In a fluid regulator, the combination of a housing having a fluid inlet and a fluid outlet, a flow controlling valve, a pressure responsive diaphragm inside said housing operatively connected with Said valve, a diaphragm vibration eliminator means yieldingly exerting pressure at a plurality of points on said diaphragm, said means comprising a body having a pluralityT of radial stems attached thereto and spaced equal distances i 4 apart, eccentric members rotatably mounted on the outer ends of the stems and having curved faces respectively engaging the diaphragm and said housing, and a tensioning spring interposed between said body and said housing.

4. In a fluid pressure regulator, the combination of a housing having a fluid inlet and a fluid outlet, a flow controlling valve, a pressure responf sive diaphragm in said housing andl operatively connected to said Valve, a member located centrally of the diaphragm, spring means for forcing said member toward the diaphragm, radial stems rigidly carried by said member, and eccentric members rotatably mounted on the outer ends of said stems and engaging the diaphragm and said housing.
